Chris Jackson/Getty Images(LONDON) — Prince William spoke candidly about fatherhood in a very emotional interview this week with Vietnam TV.

The second in line to the British throne made his first official visit to Vietnam for the Hanoi Conference on Illegal Wildlife Trade,on a mission to stop illegal poaching and the devastating effect the ivory trade has on endangered wildlife. While in Vietnam he sat down with Talk Vietnam, an English-language talk show, when he opened up about family life and his hopes for the future

“I’m very lucky in the support I have from Catherine. She’s an amazing mother and a fantastic wife,” William said speaking lovingly about Kate.

William spoke about how his children — 3-year-old Prince George and 18-month-old Princess Charlotte — have changed his life.

“I adore my children very much and I’ve learned a lot about myself and about family just from having my own children,” he said. “George is a right little rascal sometimes, he keeps me on my toes but he’s a sweet boy. And Charlotte, bearing in mind I haven’t had a sister so having a daughter is a very different dynamic. So I’m learning about having a daughter, having a girl in the family.”

William admitted there are “challenges” that go along with parenthood and he thinks quite a bit about the world his children are growing up in.

“I worry about the future more. When you have something or someone in your life to give the future to I think it focuses the mind more about what you’re giving them and are you happy that you’ve done all you can to leave it in a good state,” he said.

“I would like them to grow up with more simple aspirations. I think there’s a lot of huge aspirations and people living with an enormous amount of stuff that they don’t necessarily need,” he said. “The materialism of the world I find quite tricky sometimes.”
